Forming machines are used to produce pre-made bags. The main raw material is a roll of plastic film, paper or multi-layer laminate.
The film can be neutral or printed according to requirements (brand logo, instructions for use, etc.).
The function of the converting machine is to shape the film into a bag : it is folded, formed, sealed and cut according to pre-established specifications (dimensions, gussets, zips, perforations, handles, pre-cuts).

The “Converting” machine is mainly equiped with an in-line zipper application, where the zipper is inserted along the film. For front zip systems, the zipper is inserted crosswise or like cross web on the machine.
